Newer high definition cameras, and cameras with multiple lenses such as
the range of stereo-vision cameras now available have ever increasing
data rates.
The inclusion of a variable length packet header in URB packets mean
that we must memcpy the frame data out to our destination 'manually'.
This can result in data rates of up to 2 gigabits per second being
processed.
To improve efficiency, and maximise throughput, handle the URB decode
processing through a work queue to move it from interrupt context, and
allow multiple processors to work on URBs in parallel.

(cherry picked from commit b012186ace)
The streaming object is a key part of handling the UVC device. Although
not critical, we are currently missing a call to destroy the mutex on
clean up paths, and we are due to extend the objects complexity in the
near future.
Facilitate easy management of a stream object by creating a pair of
functions to handle creating and destroying the allocation. The new
uvc_stream_delete() function also performs the missing mutex_destroy()
operation.
Previously a failed streaming object allocation would cause
uvc_parse_streaming() to return -EINVAL, which is inappropriate. If the
constructor failes, we will instead return -ENOMEM.
While we're here, fix the trivial spelling error in the function banner
of uvc_delete().

(cherry picked from commit ece41454c6)
The buffer queue interface currently operates sequentially, processing
buffers after they have fully completed.
In preparation for supporting parallel tasks operating on the buffers,
we will need to support buffers being processed on multiple CPUs.
Adapt the uvc_queue_next_buffer() such that a reference count tracks the
active use of the buffer, returning the buffer to the VB2 stack at
completion.

(cherry picked from commit 01e90464e4)
Both uvc_start_streaming(), and uvc_stop_streaming() are called from
userspace context, with interrupts enabled. As such, they do not need to
save the IRQ state, and can use spin_lock_irq() and spin_unlock_irq()
respectively.

(cherry picked from commit c50c9c1e65)
The URB completion operation obtains the current buffer by reading
directly into the queue internal interface.
Protect this queue abstraction by providing a helper
uvc_queue_get_current_buffer() which can be used by both the decode
task, and the uvc_queue_next_buffer() functions.

(cherry picked from commit c6d664fe8a)
We currently store three separate arrays for each URB reference we hold.
Objectify the data needed to track URBs into a single uvc_urb structure,
allowing better object management and tracking of the URB.
All accesses to the data pointers through stream, are converted to use a
uvc_urb pointer for consistency.

(cherry picked from commit 811496c967)
The device information structure is currently copied field by field in
the uvc_device structure. As we only have two fields at the moment this
isn't much of an issue, but it prevents easy addition of new info
fields.
Fix this by storing the uvc_device_info pointer in the uvc_device
structure. As a result the uvc_device meta_format field can be removed.
The quirks field, however, needs to stay as it can be modified through a
module parameter.
As not all device have an information structure, we declare a global
"NULL" info instance that is used as a fallback when the driver_info is
empty.

If the Type-C PHY works as DP 4 lanes, the Tx/Rx lanes
of Type-C USB 3.0 PHY is used for DP lanes, so it needs
to force the USB 3.0 to USB 2.0 only, and make sure USB
3.0 xHCI controller doesn't support USB 3.0 port.
With this patch, an ASUS Type-C to HDMI dongle which
supports DP 4 lanes and USB 2.0 simultaneously can
